Outline of Final Research Achievements

The solubility of the wheat protein was significantly lower in the flour prepared at various heating condition (oven or autoclave). The amount of wheat antigen decreased with the heat treatment time. The amount of protein in feces was significantly higher in the rats fed heat treated gluten. These results indicated that heat treated wheat flour was useful food for abandon removal of wheat.
The flour prepared at heating on 10 minute can be applied to confectionery and noodles.
